Very nice birds! The one in the second picture looks like some sort of a silkie cross. The one in the first picture could have some barred rock in him but, I'm not sure. Neither of them look like pure breeds. Hope this information is helpful and good luck with your roosters!
Thank You Roosteraddict99 mmmm silkie cross that was my guess too...maybe a partridge cochin I'm thinking looking at the colors and feathers (that's what I've been thinking since he got some color)
But the big one has been growing like a weed (he's huge!) I thought a Copper and Cuckoo Cross but that's what I've been thinking...But he's been grwoing like a Broiler almost!
I need experts...
